Both your enemies and allies are quick to tell you what you cannot do. Your enemies wish to attack your morale and confidence. Your allies don't want to see you hurt in case your dreams do not come true. Strangers lean towards negativity, so even they will shoot your dreams down if they somehow get knowledge of what you're up to.
They are all correct. But what if your heroes listened to them? What if your favorite players took their advice? No one would ever stand out from the crowd, and there would be no one to look up to, or chase. Who told you that you are not someone else's hero? On top of that, who said that you cannot AT THE VERY LEAST, do the work that heroes do?  If you don't score 40K points in the NBA, does that mean you should give up basketball altogether? Looks crazy when you see it this way, because it is.
